Axelay

The Illis solar system has succumbed to an alien invasion, its fleet defeated save for one stubborn survivor – the righteous pilot of the powerful Axelay stratafighter. He must now go where no man has, penetrating the heart of the Armada of Annihilation to eliminate its mysterious leader. Hostile cityscapes, an aquatic underworld, even a lava planet alive with airborne worms – the game’s six worlds are as diverse as they are lethal.
